The XR46110 is an LED current controller with line regulation compensation for operating over a wide alternating current (AC) voltage source range. It can drive an external N-channel power MOSFET to regulate the current flowing through a high voltage (HV) LED string.
The XR46110 is used in series with an LED string, working as a constant current sink with linear- type overvoltage protection (OVP), linear-type over temperature protection (OTP) and line regulation compensation. It is suitable for applications with a rectified AC voltage source.
The PCB design can be very compact to meet various shape requirements. It is especially suitable for replacing incandescent light bulbs and linear-type fluorescent lamps.
